I never found instructions for windows 7 so after 2 days of testing came up with solutions that worked for me, follow these 10 steps and let me know if it works in the comments below.
You will need:
Windows 7
Wireless card
Wep hack pack (alternative)
1. Install commview: go to the commview folder in the package and double click setup, follow theinstall nothing special but once done it will fail saying it's not compatible with vista, ignore that.
2. Take the crack file and place it in C:\program files\commview\ (or program files86 if you have 64 bit windows), it will say something about overwriting accept it.
3. Next right click the file cv.exe and click properties, compatabilities and select windows xp sp3 and run as administrator.
4. Run it, now if you can click the play button your drivers work your lucky and can skip to number 7
5. Otherwise you can close the program and right click computer, manage. go to Device Manager and find your wireless card that you are using (under network adapters) now right click and Update driver software...
6. Browse, Let me pick, Have Disk, Browse
Locate the pack included and go to NewDrivers, ok it and see if it finds your drivers
If successful open the CV.exe again and you should see the play button highlighted it worked and you can continue
7. Click it and select Scan find the network you are targeting and begin the capture
Note make sure to check the logs to autosave and increase the size to 1000Mb and 100mb per log
They will be located under the program files directory of commview, LOGS
Cracking
It can take 4-8 hours of gathering packets (might be less or more depending on how lucky/unlucky you are - took me around 20 hours because of weaker signal strength), once done you can continue to crack the data to gain the passphrase shared wep key:
8. Open the logs with commview, file, export, Tcpdump files (*.cap) save whatever name you like
9. Go to the pack, aircrack, Aircrack-ng GUI.exe, browse to the files, choose 64 (or leave at 128 if determined it) and launch
10. Wait for the loading and press 1 and enter, the cracking begins and when done you should get the key.
Note to remove the colons and use just the numbers (maybe letter characters too?)Report back and let us know in the comments below.
Done...
